Мы тесно сотрудничаем с нашим нынешним заказчиком РН Vulcan, компанией Sierra Space, в ходе подготовки ко второму сертификационному запуску (Cert2), и хотя ULA будет готова к полету, Sierra Space сообщила, что они добились успехов в подготовке Dream Chaser, но при запуске в указанные сроки есть высокие риски не уложиться в график.

Учитывая эту задержку и неотложные потребности национальной безопасности, мы придаём высокий приоритет миссии Cert2, чтобы обеспечить сертификацию РН для запуска нашей первой космической миссии для национальной безопасности.
 
В рамках миссии Cert2 мы планируем выполнить запуск инертной полезной нагрузки (т. е. ГВМ aka ГММ) с экспериментами и демонстрациями.

Мы работаем с компанией Sierra Space, чтобы определить следующую доступную дату запуска.

ULA осознает повышенную угрозу, с которой сталкивается страна в космосе, и серьезно относится к критической обязанности по своевременному выводу на орбиту важнейших космических аппаратов, предназначенных для обеспечения национальной безопасности.

The second United Launch Alliance (ULA) Vulcan rocket stands fully assembled for launch no earlier than Oct. 4 to fulfill flight test obligations and complete its certification process with the U.S. Space Force to carry national security payloads starting later this year.

Liftoff will occur from Space Launch Complex (SLC)-41 at Cape Canaveral Space Force Station in Florida during a launch window of 6 to 9 a.m. EDT.

This second Certification (Cert-2) (https://www.ulalaunch.com/missions/next-launch/vulcan-cert-2) launch will demonstrate Vulcan's high-energy rocket architecture by achieving an Earth-escape trajectory and placing the Centaur V with an inert, non-deployable payload into deep space where it will orbit the sun for the rest of time. Cert-2 follows Vulcan's successful inaugural launch on Jan. 8, 2024.

The mission will further demonstrate the operational capabilities of Vulcan, perform unique experiments and run complex demonstrations for potential incorporation into future missions. 

"After the key objectives necessary for certification are completed, the mission will evaluate additional changes to design of the upper stage and how it is operated over long coast periods to further increase its endurance," said Mark Peller, ULA's senior vice president, Vulcan Development and Advanced Programs.

This Vulcan rocket, designated V-002, was built in ULA's unique rocket factory in Decatur, Alabama, then shipped to the Florida launch site aboard the R/S RocketShip.

The launch campaign at the Vertical Integration Facility-G (VIF-G) began Aug. 10 when the Vulcan booster stage was hoisted aboard the mobile Vulcan Launch Platform (VLP). The stage measures 109 feet (33 meters) in length and 17.7 feet (5.4 meters) in diameter. Made of internal orthogrid aluminum construction to create a structurally stable stage, it is equipped with two BE-4 main engines, each producing approximately 550,000 pounds (2.45 mega-Newtons) of thrust to lift Vulcan out of the atmosphere on the way to orbit.

^{A GEM63XL is maneuvered into position for attachment to Vulcan. Photo by United Launch Alliance}

A pair of Graphite Epoxy Motor (GEM) 63XL solid rocket boosters (SRBs) were added to the sides of the first stage on Aug. 13 and Aug. 14. Measuring 63 inches (1.6 meters) in diameter and 72 feet (21 meters) in length, each motor is filled with over 100,000 pounds (45,360 kg) of aluminized solid propellant to deliver 463,249 pounds (2.1 mega-Newtons) of thrust at its peak.

Together, the methane-fueled main engines and SRBs will provide the 2 million pounds (8.9 kilo-Newtons) of thrust generated at liftoff to power Vulcan off the launch pad.

The high-performance Centaur V upper stage -- 38.5 feet (11.7 meters) long and 17.7 feet (5.4 meters) in diameter -- was installed atop the rocket on Aug. 17. With its pressure-stabilized stainless-steel tanks, the cryogenic stage features two RL10C-1-1A engines, each producing 23,825 pounds (106 kilo-Newtons) of thrust to shape the mission's final orbital destination.

The Cert-2 payload, already encapsulated in the composite fairing measuring 17.7 feet (5.4 meters) in diameter and 51 feet (15.5 meters) in length, was moved from the off-site preparation facility to the VIF-G adjacent to SLC-41 on Sept. 21.

ULA technicians attached the lifting sling to the payload and hoisted it into the VIF for connection to the Centaur V upper stage of the Vulcan rocket, which now stands fully assembled at 202 feet (61.6 meters) tall. 
 
Integrated testing and a complete electrical checkout of the combined rocket and payload will be completed in the coming days while final readiness reviews and closeout activities are performed in preparation for rollout of the rocket on its VLP to SLC-41 for a Wet Dress Rehearsal, followed by the countdown and liftoff. 
This is the second of two flight tests required for ULA's certification process with the U.S. Space Force. ULA has worked in close partnership with the Space Force throughout the design, development, testing and production of the next-generation rocket for assured access to space. The Space Force selected Vulcan as the No. 1 offeror and "best value" choice in the Phase 2 National Security Space Launch (NSSL) competition. 
Vulcan incorporates the best attributes of the venerable Atlas and Delta heritage rocket families and introduces innovative technologies and streamlined processes, creating one launch solution that meets the demanding requirements for launching critical national security missions to the full spectrum of orbits.

ЦитироватьUnited Launch Alliance Successfully Launches Second Vulcan Certification Flight
Cape Canaveral Space Force Station, Fla., (October 4, 2024) – United Launch Alliance (ULA) ushers in a new era of space capabilities with the successful launch of its second certification flight (Cert-2) of the next generation Vulcan rocket on Oct. 4 at 7:25 a.m. EDT from Space Launch Complex-41 at Cape Canaveral Space Force Station.

"The success of Vulcan's second certification flight heralds a new age of forward-looking technology committed to meeting the ever-growing requirements of space launch and supporting our nation's assured access to space. We had an observation on one of our solid rocket boosters (SRB) that we are reviewing but overall, we are pleased with the rocket's performance and had a bullseye insertion," said Tory Bruno, ULA's president and CEO. "Vulcan provides high performance and greater affordability while continuing to deliver our unmatched reliability and orbital precision for all our customers across the national security, civil and commercial markets."

The Cert-2 mission carried experiments and demonstrations associated with future capabilities of Centaur V, the world's highest-performing upper stage designed to further deliver on ULA's unrivaled legacy of reliability and precision. Centaur V provides 2.5 times the energy and 450 times the endurance of its predecessors, enabling the most complex orbital insertions within the most challenging and clandestine orbits.

"Vulcan is built with the strength of a national workforce whose unmatched dedication and innovation has modernized the very best of our industry-leading heritage," said Mark Peller, vice president of Vulcan Development. "The foundation of Vulcan's purpose-built design rests on the best of what we've learned from more than 120 combined years of launch experience with Atlas and Delta."

The Cert-2 mission served as the second of two certification flights required for the U.S. Space Force's certification process and ULA has now completed all requirements for certification. ULA continues to work closely with the U.S. Space Force as they take the next few weeks to review the data and compare it to ULA's first certification mission to ensure that the vehicle performed as expected and there are no additional items that need review. Once the evaluation is complete to the Space Force's standards, the Vulcan rocket will be certified to launch national security missions.

"The team will continue to modify our infrastructure as we work towards an accelerated launch cadence to meet our customers' manifest requirements while building off today's successful launch and developing future Vulcan upgrades, including SMART reuse plans for downrange, non-propulsive recovery of Vulcan engines," said Bruno.

ULA has sold more than 70 Vulcan launches to date, including 38 missions for Amazon's Project Kuiper and multiple national security space launch missions as the part of the country's Phase 2 launch procurement.

All rockets are not created equal. ULA is the nation's most experienced, reliable and accurate launch service provider delivering unmatched value, a tireless drive to improve, and commitment to the extraordinary. Vulcan's inaugural launch marked the beginning of a new era of space capabilities and provides higher performance and greater affordability while offering the world's only high energy architecture rocket to deliver any payload, at any time, directly to any orbit.

А в "Прикладную" каким боком?
Если действительно миссия стерильная, то - в Средства выведения.
Но очень не хочется. Слабая надежда на то, что всё таки подгрузят "unique experiments" "into deep space". ( #2 (https://forum.novosti-kosmonavtiki.ru/index.php?msg=2670751))

Space Force shows the initial parking orbit of Vulcan Cert-2 as 492 x 498 km x 30.0 deg. I request asteroid observers to look out for the 5 metre diameter Centaur (and attached dummy payload) in its hyperbolic escape orbit.

Well, hmm...

Bullseye chart coming. I imagine some of you are especially curious:  orbital insertion was perfect

Cosmic Penguin  @Cosmic_Penguin
The reduced & asymmetric thrust part is as expected, but good to see confirmation.

Tory Bruno  @torybruno
Replying to @certifiedbafoon
Yes
Nozzle anomaly on SRM-1. Reduced and asymmetric thrust.
Rocket compensated, as designed.
Nominal trajectory. Bullseye insertion

Cosmic Penguin  @Cosmic_Penguin
Will be interesting to see if @SpaceForceDoD gives their ticks of approval quickly based on this:

Tory Bruno  @torybruno
Replying to @SpaceXplorerXVI and @Karmaycholera
Incorrect. Rocket performed as designed, compensating for the reduced thrust from SRM #1. Propellant consumption was within baseline (always present) reserves and margins (based on payload mass) were unaffected

Cosmic Penguin  @Cosmic_Penguin
Just to note that it is definitely possible that:
* A wider margin of propellant usage, and thus reserve, is used on this test flight
* The SRB problem might really didn't affect thrust *that* much to cause problems this time.

Tory Bruno  @torybruno
Yes
 Sorry about the confusing terms on art.
All missions have propellant reserves
We add to that additional propellant margins based on the mass & the configuration of the rocket
Because this was compensated for within reserves, this anomaly was "invisible" to the rocket

And here's the Bullseye plot. #CERT2 #VulcanRocket

Похоже, три сигмы.

Цитата: Arzach от 06.10.2024 11:54:16похоже на прогорание корпуса над соплом

Цитата: Штуцер от 06.10.2024 14:27:29Да. Где то в месте соединения нижнего днища и обечайки.
По идее дыра должна разгораться и быстро.

Цитата: anik от 05.10.2024 13:26:52Красные точки посередине графика означают, что отклонений от расчётных значений по перигею, наклонению, аргументу перигея и отлётной скорости нет либо они минимальны.

То есть маленькая масса полезной нагрузки вкупе с большими резервами компонентов топлива позволили ракете-носителе даже при «отделившемся сопле» бокового ускорителя обеспечить точное выведение на отлётную траекторию.

Цитата: opinion от 06.10.2024 21:27:56Скорее всего, прогар в месте соединения керамического насадка с металлической частью сопла.

Цитата: Дем от 07.10.2024 11:56:51А тут сопло фиксированное или управляемое?

Повезло что прогар был в наружном направлении, а то бы знатно бабахнуло как на Челленджере. 

Цитата: Arzach от 07.10.2024 22:47:22На этом уровне прогар даже во внутреннем направлении вряд ли привёл бы к повреждению бака. Вот если бы выше...

Цитата: Astro Cat от 04.10.2024 20:57:12Я так понимаю, сертификация провалена? Да FAA? Или это другое?

Бруно делает вид, что всё штатно. Ну, подумаешь, сопло отвалилось. Мелкая неприятность. Военные поздравили и аномалию не упомянули. В FAA сказали, что про аномалию в курсе, но пока не решили, нужно ли её расследовать или так сойдёт.

Это все же достаточно независимая подсистема, наверняка контрактор делает, так что терпимо.
